I got a kel tec sub 2000 9 mm glock 17 mag model. It's pretty nifty, a pistol caliber carbine that folds in half for easy storage. It takes the same mags as my pistol, for double win. I got it to the range and all was well. I got about two mags through it, then the front sight broke. Yeah, the piece of plastic that served as a post just snapped and kept flying forward with every shot. It seemed solid other than not, you know, being able to aim any more. Sigh.
